Diagnostic of H.pylori infection requires several methods, some of them are currently used in “Institut Pasteur “of Algeria. The aim of this study is to evaluate performances of two enzyme immunoassays used in detection of H.pylori using stool Ag before and after eradication, the first one “premier Platinium HpSA, Meridian Diagnostics” use a polyclonal Ac, the other one “IDEA HpStAR, Oxoid” use...

Single crystals of the title compound, aluminium niobium triphosphate, Al(0.5)Nb(1.5)(PO(4))(3), have been synthesized by a high-temperature reaction in a platinium crucible. The Al(III) and Nb(V) atoms occupy the same site on the axis, with disorder in the ratio of 1:3. The fundamental building units of the title structure are isolated Al/NbO(6) octa-hedra and PO(4) tetra-hedra (. 2 symmetry),...

Small cell carcinoma of the urinary bladder is an uncommon tumor that has been described in case reports or small series. We report a new case in a 67-year-old male who presented with gross hematuria and irritative symptoms. Cystoscopy revealed an extensive mass of the bladder and computed tomography scan showed an important thickening of the bladder wall. Diagnosis of small cell carcinoma was ...

Polycrystalline material of the title compound, AgInP(2)O(7), was synthesized by traditional high-temperature solid-state methods and single crystals were grown from the melt of a mixture of AgInP(2)O(7) and B(2)O(3) as flux in a platinium crucible. The structure consists of InO(6) octa-hedra, which are corner-shared to PO(4) tetra-hedra into a three-dimensional network with hexa-gonal channels...

We have designed low noise temperature sensing and control units with the objective of using them for the fabrication of far infrared active cavity radiometers. The sensing unit, first characterized at 300 K using industrial platinium resistance thermometers, has a noise level of ∼ 25− 30 μKeff for a 3 hours measuring time and in a 1 Hz bandwidth. Using YBCO superconducting thermometers, the no...
